Jason vs The Ultimate LEGO Machine

Custom designed Ultimate Machine (also known as a Useless Machine) built using the new LEGO Mindstorms EV3 kit. I call it the LuuMa EV3.

It's a little bit more elaborate than the traditional ultimate machine, featuring 6 different responses for turning the switch off and 2 evasive maneuvers for trying to prevent the switch from being turned on in the first place.
Step by step instructions for building the core (which only uses parts from the 31313 LEGO Mindstorms EV3 kit) can be found on my website (http://www.truedimensions.com), along with the Mindstorms project file for running the program. I haven't provided instructions for building the box, as it really is pretty much just a box.
I had a lot of fun with this one, especially programming the various responses. As always, let me know in the comments what you think, and if there are any other cool mechanical creations you'd like to see built out of LEGO!
